probabilitiesFromCounts R Documentation
Helper function to calculate probability from counts in dplyr friendly manner
Description
The purpose of this is to calculate the probabilities of given all binary outcomes from
a table of marginal frequencies in a dplyr friendly way.
Usage
probabilitiesFromCounts(df, x1y1Var, x1Var, y1Var, totalVar)
Arguments
df
a dataframe containing one observation per row
x1y1Var
the datatable column containing frequency of cooccurrences of events x1 and y1 (true positives)
x1Var
the datatable column containing frequency of occurrences of event x1 (observed positives)
y1Var
the datatable column containing frequency of occurrences of event y1 (predicted positives)
totalVar
the datatable column containing total number of events (all observations)
Value
the datatable with additional columns for all the probabilities associated with each outcome (i.e. a 2x2 confusion matrix)
